Buy, Rehab, Rent, Refinance, Repeat
BRRRR Calculator
Know Your Cash Left in the Deal Before You Buy
Auto ARV from comparable sales, rent estimated from real comps, and the full refinance waterfall - purchase to cash-out - in seconds. No spreadsheet required.
The deal in, the refinance verdict out, an AI second opinion
The whole BRRRR strategy lives or dies on one number: how much of your cash comes back at the refinance. We calculate it before you make the offer.
How the BRRRR Analysis Works
Five stages, one connected model - each letter feeds the next
Buy
Purchase price plus your acquisition financing - hard money, bridge loan, or all cash
Rehab
Renovation budget with a contingency buffer, plus carrying costs while the work happens
Rent
Rent estimated from real comparable rentals in the area - not a guess
Refinance
New loan = ARV x LTV. It pays off the bridge loan and shows your exact cash out
Repeat
See the cash left in the deal and how much capital you recycled for the next one
It all flows through the refinance waterfall
Every BRRRR lives or dies on the same chain of numbers: what you put in to buy and rehab, what the property appraises for, what the new loan returns, and what stays stuck in the deal. Do it by hand and you're juggling a spreadsheet of loan math, comps, and closing costs.
The calculator runs this exact waterfall for you - ARV from comparable sales, rent from real comps, bridge payoff, refi closing costs - and lands on the one number that matters before you ever make the offer.
The Refinance Waterfall
Down payment + rehab + carrying costs
ARV $175,000 x 75% LTV
After the $90,000 bridge payoff + refi costs
Your real basis in a cash-flowing rental
Example numbers for illustration. The calculator runs this waterfall with your deal's actual figures.

Cash Left in Deal
Cap rate and cash flow matter - but for BRRRR, capital recycling is the whole game
Why capital recycling wins
A traditional rental purchase locks your down payment into one property. BRRRR gets most of it back at the refinance, so the same capital buys the next property - and the one after that.
The less cash you leave in each deal, the faster your portfolio compounds. That's why the calculator makes cash-left-in-deal the headline result of every analysis, computed from the actual refinance waterfall - not a rule of thumb.
The infinite-return case, handled honestly
When the refinance returns more cash than you put in, your cash-on-cash return is technically undefined - you have no cash left invested. Some tools print a misleading percentage anyway.
We don't. When the refi returns more than you put in, we show the surplus - not a fake percentage. You'll see exactly how many dollars came back above your investment, alongside the cash flow the property produces from day one.
The Verdict
Know in Seconds Whether to Keep Going
Most deals are not BRRRR deals, and the sooner you know, the more time you keep for the ones that are. The summary opens with a straight answer on whether this property clears the bar lenders refinance against.
- A BRRRR-Ready verdict the moment the numbers land — no spreadsheet to interpret
- All-in cost against ARV on one gauge, so you see how much room the 75% rule leaves
- The whole cash story in three cards: You Put In → Refi Returned → Left In Deal
When It Does Not Work
A Dead Deal Turns Into an Offer
When a property misses, the answer is rarely “walk away” — it is “not at this price”. So instead of stopping at a red verdict, you get the price that would make it work, and a wasted evening turns into an offer.
- The maximum purchase price that still recovers all of your capital — a number you can send
- A plain warning the moment all-in cost passes 75% of ARV, before you spend an evening on it
- How far off the deal is in dollars, not just a pass or a fail
Everything You Need to Say Yes or Walk Away
A BRRRR fails in slow motion — at the appraisal, at the rent, at the refinance. Each screen below removes one of those surprises while the deal is still a decision instead of a mortgage.
Deal Inputs
Enter the Deal Once — the Whole BRRRR Solves Itself
A BRRRR is four decisions — what you pay, what you spend, how long you hold, and what the bank hands back — and every one of them moves the others. Set them on one screen and they resolve together, so you stop rebuilding a spreadsheet for every property and start judging every deal the same way.
- The after-repair value arrives already estimated, so you are not hunting comps to get started
- Your lender's terms, not a template — set the LTV, rate, term and closing costs you were actually quoted
- A rehab budget with the contingency you choose, so you underwrite what you would really spend
- Rehab and seasoning months carry their own holding costs — the line most spreadsheets forget
Cash Flow Analysis
Find Out the Rental Loses Money Before You Own It
The property you end up holding is not the one you bought; it carries a bigger loan at a higher value. This is where you meet that property before your money is committed. A deal that only works until the new mortgage starts has nowhere left to hide.
- Judged against the refinance loan you will actually carry, not the money you bought with
- Rent comes from real nearby rentals, with a confidence range that tells you how far to trust it
- Vacancy, repairs, capex and management are yours to set, so the cash flow is one you believe
- Change the rent and the whole picture moves — stress-test the deal in seconds
Multi-Year Projections
See What the Cash You Left Behind Actually Earns
After a refinance most of your money is back out of the deal, which is exactly why an ordinary return calculation misleads you here. Measure the return on what is still in the property and a BRRRR that looks unremarkable anywhere else can turn out to be the best thing you own.
- Returns measured on the cash still in the deal — the only basis that means anything after a refinance
- Your assumptions on rent growth, expenses, appreciation, taxes and selling costs
- Equity and cumulative cash flow carried out to year 30, so hold-or-sell stops being a feeling
- A return for every exit year, so you can see the moment selling starts to beat holding
Rental Comparables
Defend Your Rent Number Before a Lender Questions It
Rent decides whether the bank writes the loan and whether you keep anything afterwards, so it is the last number you should take on faith. Seeing the evidence — and being able to correct it — is the difference between a rent you hope for and one you can point at.
- See the rentals the estimate was built from instead of trusting a black box
- Drop a comp that is nothing like your property and the whole analysis re-solves
- The same rental data behind the Rent Estimator, so your numbers agree across the app
- A confidence range tells you how much weight the estimate can carry
ARV Comparables
The Number Your Refinance Depends On — With the Receipts Attached
Your entire plan rests on an appraiser agreeing with your after-repair value. Seeing the sales behind that number lets you find the weak assumption now, while walking away still costs you nothing — instead of on the day the appraisal lands low and the loan shrinks with it.
- Every comparable sale behind the value, closest matches first
- Exclude one that is not a renovated home and the loan amount and cash left in update with it
- Labelled as a market model rather than an appraisal, so you know what you are holding
- A stretched value gets flagged before you build a plan on top of it
The Checks That Keep a BRRRR From Going Sideways
Most BRRRR failures happen at the refinance. We flag the risks before you commit.
Refi Coverage Check
Does the new loan actually cover your bridge payoff and refinance costs? If the numbers say you'd need to bring cash to the closing table, you'll know before you buy - not at the closing.
DSCR Lender Check
Refinance lenders check whether the rent covers the new mortgage payment. We calculate the debt service coverage ratio on the post-refi loan and warn you when it falls below 1.2 - the threshold where many lenders shrink the loan or walk away.
Appraisal Risk Awareness
The whole plan depends on the appraisal hitting your ARV. Our ARV comes with a confidence range from the comp data, so you can see how much cushion you have if the appraiser comes in low - and stress-test the deal at the bottom of the range.
Then AI reads the deal
Beyond the guardrail math, AI reviews the whole picture: refinance risk broken into appraisal, DSCR and seasoning, a BRRRR fit score, and ranked risk factors with concrete mitigations - including the honest call when a different strategy beats BRRRR on this property.
AI Insights
A Second Opinion Willing to Tell You to Walk Away
The expensive mistakes are the deals that were nearly good. This reads the whole analysis the way an experienced partner would and gives you the verdict you may not want — including that the property is worth buying, just not as a BRRRR. One avoided deal pays for the year.
- A fit score out of 10, and the strategy that beats BRRRR on this property when one does
- Refinance risk split into appraisal, rent coverage and seasoning, so you know which one to fix
- Risks ranked with a specific mitigation for each, not a page of vague warnings
- Re-run it after you change the rent, the rehab or the refinance terms

Why a BRRRR Calculator Matters Before You Buy the First Property
The BRRRR method - Buy, Rehab, Rent, Refinance, Repeat - is the strategy investors use to build a rental portfolio with the same pool of capital: buy a distressed property below market, renovate it, rent it, then refinance at the new appraised value so the cash-out loan returns most or all of what you put in. When it works, the money that bought house one buys house two. When it misses - an ARV the appraiser will not support, a rehab that runs over, rent that leaves the debt service coverage ratio under what the refinance lender requires - the shortfall stays trapped in the deal, and the strategy stalls on property one.
A BRRRR calculator makes that outcome visible before the offer. It runs the refinance waterfall - all-in cost, new loan at the lender's LTV, cash returned at closing, cash left in the deal - and shows the purchase price that would make the deal a full capital recovery. This one goes further than a spreadsheet: the after-repair value is estimated from comparable sales you can review and exclude, the rent from real rental listings with a confidence range, and the stabilized rental is checked the way a lender checks it, with DSCR, seasoning and appraisal risk flagged. Then the AI reads the whole picture and says whether BRRRR is even the right strategy for that property.
What Is the Refinance Waterfall?
Your all-in cost - purchase, rehab, contingency, closing and carrying costs through the rehab and seasoning period - goes in; the new loan at the lender's loan-to-value comes out; whatever the loan does not cover is the cash left in the deal. On a $439,000 ARV at 75% LTV the new loan is $329,250. If your all-in is $383,304, roughly 84% of your cash comes back and $60,639 stays invested. The calculator shows every step, not just the answer.
Why Does the 75% Rule Decide the Deal?
Most cash-out refinance lenders cap the new loan at about 75% of appraised value, so the all-in cost has to land at or under 75% of ARV for the loan to return everything. The calculator shows your all-in as a percentage of ARV on a gauge with a BRRRR-Ready / Over Budget verdict, and the maximum purchase price that would get you to full capital recovery - the number to negotiate toward.
What Is DSCR and Why Do Refinance Lenders Check It?
Debt Service Coverage Ratio is the property's net operating income divided by the new loan's annual payments; lenders typically require 1.2 or better. A deal can pass the 75% rule and still fail DSCR if the rent is thin, and then the refinance does not close at all. The calculator models the stabilized rental after the refinance - rent from comparables, expenses and the new payment - and warns when DSCR falls below the lender minimum.
How Should You Measure a BRRRR Return?
On the cash left in the deal, not the down payment. If $250 stays invested and the property cash-flows, the return is effectively infinite; if $60,000 stays invested and the rental loses $1,000 a month, it is a bad deal however the refinance looked. The multi-year projections use cash left in as the investment basis and the all-in cost as the tax basis - and the AI insights say plainly when a flip or a straight rental beats BRRRR on that property.
